Note
* 1. All voltage reference ground level: 0V
* 2. Applied to the VCOVDD / PVDD / CPVDD pins
* 3. Applied to the CPVSS / PVSS / VCOVSS / OAVSS pins
* 4. Applied to the VCNT / REFIN pins
* 5. Applied to the CLK / DATA / LE / PDN1 / PDN2 / TEST1 / TEST2 pins
* 6. The maximum value must not exceed the absolute maximum rating of 3.6V.
Exceeding these maximum ratings may result in damage to the AK1573. Normal operation is not
guaranteed at these extremes.
